CHAPTER 1

INTRODUCTION TO THE MEDICAL THREAT Section I. MESSAGE TO THE UNIT COMMANDER
DISEASE AND NONBATTLE INJURY A DNBI casualty can be defined as a military person who is lost to an organization by reason of disease or injury, and who is not a battle casualty. This definition includes persons who are dying of disease or injury due to accidents directly related to the operation or mission to which they were deployed. The acronym, DNBI, does not include service members missing involuntarily because of enemy action or being interned by the enemy (as a prisoner of war). The total number of DNBI casualties is evaluated to identify DNBI rates per number of service members in an operation. The DNBI rates are critical in evaluating the effectiveness of PVNTMED missions within the area of operations (AO) and in determining the health of a force within an operation. Historically, in every conflict the US has been involved in, only 20 percent of all hospital admissions have been from combat injuries. The other 80 percent have been from DNBI. Excluded from these figures are vast numbers of service members with decreased combat effectiveness due to DNBI not serious enough for hospital admission.

percent of the artillerymen contracted a disease called filariasis transmitted by mosquitoes. Both units had to be replaced (medically evacuated) without seeing any enemy action because they were not combat ready. The use of insect repellents and insecticides and the elimination of standing water would have prevented this. Merrills Marauders: Disease was an important detractor to this famous unit. The medical threat faced by the Marauders in the jungles of Burma was great. Everyone was sick, but some had to stay and fight. Evacuation was limited to those with high fever and severe illness. One entire platoon cut the seats from their pants because severe diarrhea had to be relieved during gunfights. After a bold and successful attack on a major airfield, Merrills Marauders were so decimated by disease that they were disbanded.

PRINCIPLES OF PREVENTIVE MEDICINE MEASURES    Service members perform individual techniques of PMM. Chain of command plans for and enforces PMM. Field sanitation teams train service members in PMM and advise the commander and unit leaders on implementation of unit-level PMM. Failure to Apply the Principles of PMM Can Result in Mission Failure.

CHAPTER 2

INDIVIDUAL PREVENTIVE MEDICINE MEASURES Section I. HEAT INJURIES
OVERVIEW Heat injuries can occur anywhere, depending on physical activity (work rate) and clothing worn. However, they occur most frequently during warm-weather training, exposure to high climatic temperatures, high humidity, and bright sunlight. These conditions make it difficult for the body to regulate its temperature. Hot weather also increases daily water requirements, because body water is lost as sweat. Dehydration leads to added heat stress, increased susceptibility to heat injury, reduced work performance, and degraded mission capability. ACCLIMATIZATION When the mission permits, all personnel should work and exercise in a manner so that they gradually become acclimatized to the heat and humidity in the AO. Significant heat acclimatization requires at least

DunlapTattler.com public docs made public

2-1

FM 21-10/MCRP 4-11.1D

3 to 5 days and full acclimatization can take up to 2 weeks. Exercising in the heat and humidity for 1 to 2 hours daily, gradually increasing the workload each day, can produce acclimatization. (Refer to Table 3-1 in Chapter 3.) When the mission does not permit time for gradual increases in workload, then leaders and buddies must observe each other and ensure that everyone drinks plenty of water during each work period. Individuals leaving a cold or cool climate will require additional time to become acclimatized to a hot climate. DRINK PLENTY OF WATER Depending on the heat and activity level, you may need to drink from 1/2 to 11/4 quarts of water per hour3 gallons/12 liters per day in hot, dry climates. Drinking water is a must in order to prevent heat injury. If desired, individuals may add flavoring to the water to enhance consumption. Field rations/meal(s), ready to eat (MRE) have flavoring for water in each meal. It the flavoring is used, add it to water in your canteen cup. Do not add flavoring to the water in your canteen; it increases the risk of contamination and illness. Never flavor the bulk source water supply. (Flavoring the bulk source water supply will reduce the action of water disinfectants.) See Table 3-1 for water intake requirements.   Drink extra water before starting any mission or hard work. Cool water (60° to 70° Fahrenheit [F]) is absorbed faster than cold water. Drink small quantities of cool fluids frequently. Carbohydrate/electrolyte beverages (sport drinks) may provide supplemental nutrients under conditions of extreme calorie and water requirements; such as extremely vigorous activity. However, they cannot replace and must not be used to meet all water requirements.

2-2

FM 21-10/MCRP 4-11.1D



Drink non-caffeinated fluids even if you are not thirsty. (Caffeine increases water requirements in all environments.) Refill your canteens at every opportunity, using only treated water, if possible.



NOTE The color and volume of the urine steam are good indicators of a service members hydration status. If your urine stream is dark yellow and the volume is small, or if you are constipated and experience hard stools, you may not be drinking enough water. Maintain a urine stream that is clear or light yellow. Thirst is not a good indicator of dehydration during physical activity.

USE WORK/REST CYCLES  Work and rest as your leader directs. (See Table 3-1.) A rest period helps prevent dangerous increases in body temperatures by minimizing heat production. Work and rest in the shade, if possible.

EAT ALL MEALS TO REPLACE SALTS Eating all meals in the field will usually provide the bodys requirements for salts. Field rations/MRE meet the daily requirements for minerals and electrolytes (sodium). DO NOT take extra salt in meals unless medically indicated. NOTE DO NOT TAKE SALT TABLETS. One salt tablet increases your water requirement by at least a pint. Salt draws water from muscles to dilute your blood. Salt tablets can cause vomiting.

Cover all skin exposed to sun; wear sunscreen and lip balm with a sun protection factor of 15 or higher. Protect the eyes from UV with UV-protective sunglasses, especially wraparound sunglasses. Seek shade when resting outdoors. Keep clothing loose at the neck, wrists, and lower legs. NOTE When the threat from biting arthropods is high, keep your shirtsleeves rolled down and pants bloused in boots.

Section II. COLD INJURIES
OVERVIEW Cold injuries are most likely to occur when an unprepared individual is exposed to winter temperatures. They can even occur with the proper planning and equipment. The cold weather and the type of operation in which the individual is involved impact on whether a service member is likely to be injured and to what extent. The service members clothing, physical condition, and mental makeup are also determining factors. Well-disciplined and well-trained service members can be protected, even in the most adverse conditions. Service members and their leaders must know the hazards of exposure to the cold. They must know the importance of personal hygiene, exercise, care of the feet and hands, and the use of protective clothing. Cold injuries may be divided into freezing and nonfreezing types. A freezing type is frostbite. The nonfreezing types are chilblains, trench foot, and immersion foot. (See FM 21-11.) 
2-6

Frostbite can occur when the temperature is at or near freezing or colder. Frostbite can also occur when the skin is exposed to winds of less than five miles per hour and actual temperature readings of 30° F.

DunlapTattler.com public docs made public

FM 21-10/MCRP 4-11.1D



Trench foot (and immersion foot) results from prolonged exposure to a wet, cold condition, or the outright immersion of the feet in water with a temperature usually below 50° F. At the upper range of temperatures, exposure of 12 hours or more will cause injury. Shorter duration at or near 32° F will cause the same injury. A trench foot injury is usually associated with immobilization of the feet.

Keep moving, if possible. Exercise your big muscles (arms, shoulders, trunk, and legs) frequently to keep warm. If you must remain in a small area, exercise your toes, feet, fingers, and hands. Avoid the use of alcohol as it makes your body lose heat faster. Avoid standing directly on cold, wet ground, when possible. Avoid tobacco products. The use of tobacco products decreases blood flow to your skin. Eat all meals to maintain energy. Drink plenty of water and/or warm nonalcoholic fluids. Dark yellow urine means you are not drinking enough fluids! You can dehydrate in cold climates too! Buddies should monitor each other for cold weather injury.

FM 21-10/MCRP 4-11.1D

PROTECT YOUR FEET   Bring several pairs of issue boot socks with you. Keep socks clean and dry. Change wet or damp socks as soon as possible. Socks can become wet from sweating. Apply foot powder on feet and in boots when changing socks. Wash your feet daily, if possible. Avoid tight socks and boots (completely lace boots up as loosely as possible). Wear overshoes to keep boots dry. NOTE A decrease in physical activity reduces the exposure time necessary to produce injury. In all types of footgear, feet perspire more and are generally less well ventilated than other parts of the body. Moisture accumulates in socks, decreasing their insulating quality. The feet are susceptible to cold injury and are less frequently observed than the remainder of the body. PROTECT YOUR HANDS  Wear gloves with inserts, or mittens with inserts.

  

Warm hands under clothing if they become numb. Avoid skin contact with snow, fuel, or bare metal. Waterproof gloves by treating with waterproofing compounds, such as snow seal.

PROTECT YOUR FACE AND EARS     Cover your face and ears with a scarf or other material, if available. Wear your insulated cap with flaps down or wear a balaclava and secure under your chin. Warm your face and ears by covering them with your hands. Do not rub face and ears. Do not use face camouflage when windchill is -10° F or below; prevents detection of cold weather injury (frostbite). NOTE Rubbing cold extremities can be potentially harmful. Frostbitten areas that are rubbed can cause additional injury to the affected areas.  
2-10

Wear sunscreen. Solar UV exposure is doubled when you are surrounded by snow. Exercise facial muscles.

PROTECT YOUR BUDDY  Watch for signs of frostbite on the service members exposed skin. The affected skin will appear as pale/ gray/waxy areas (it may be hard to see these changes in poor lighting or on service members with dark skin). Ask the service member if his feet, hands, ears, or face are numb and need rewarming.



DO NOT let the service member sleep in or near the exhaust of a vehicle with the engine running. DO NOT let the service member sleep in an enclosed area where an open fire is burning NOTE Service members may check circulation in the fingers and the toes by pinching the nail beds and checking how fast the color returns in the beds under the nails. The slower the return to a natural color, the more serious the potential for frostbite on the fingers and the toes. NOTE See GTA 8-6-12 and FM 21-11 for information on cold injury first aid procedures. During extended activities in a cold environment, warming areas should be provided; for example, a service member performing guard duty.

Section III. ARTHROPODS AND OTHER ANIMALS OF MEDICAL IMPORTANCE
OVERVIEW Poor sanitation and improper waste disposal under wartime conditions greatly increase the disease vector potential of such common pests as filth flies and rodents. Even in mobile field situations these camp followers have historically amplified sanitation problems, often resulting in epidemics of diarrheal diseases that have caused many casualties. This threat is even greater in urban areas converted to temporary or semipermanent military use. A dangerous temptation in field training or in deployment operations is to ignore the field sanitation standards. Some people think, The rules dont apply here. Yielding to that temptation can cost your health and the health of those around you. There is no excuse for forgetting to bring protective equipment or failing to use it. Be sure to follow all safety precautions on all labels of the pesticides that you use. They are there for a reasonto protect your health. USE THE DEPARTMENT OF DEFENSE INSECT/ARTHROPOD REPELLENTS The concurrent use of a skin insect repellent (N, N-diethyl-M-toluamide [DEET], NSN 6840-01-284-3982) and a clothing insect repellent (permethrin [NSN 6840-01-278-1336 and 6840-01-345-0237]) is necessary to obtain maximum protection against insects/arthropods.

FM 21-10/MCRP 4-11.1D

APPLY N, N-DIETHYL-M-TOLUAMIDE       Apply DEET insect repellent to all exposed skin. Follow label directions. Apply a light, even coating to exposed skin, not under clothing. DO NOT apply to the eyes and lips, or to damaged skin. One application may last 8 to 12 hours; if you receive bites, reapply a light uniform coating of repellent. Application of DEET can be safely used with camouflage face paint. Apply a thin layer of DEET first, then apply face paint.

NOTE Reapplication of DEET may be necessary (check container label) due to heavy sweating, or after river-crossing operations, exposure to rain, or in locations where arthropod density is very high.

FM 21-10/MCRP 4-11.1D

APPLY PERMETHRIN CLOTHING REPELLENTS TO FIELD UNIFORMS/ SLEEPING EQUIPMENT   Permethrin is the most effective clothing repellent available. Treat military field uniforms, including Nomex®/Kevlar uniforms, tent liners, ground cloths, and bed nets with permethrin. This should be done before wearing in field training or military operations. Follow label instructions when applying to clothing. Permethrin will remain in the material after repeated washings. Treated uniforms can be safely worn in the rain or when crossing rivers or streams. NOTE Permethrin does not rinse out in cold water (or rain or streams).    DO NOT apply directly to skin, to underwear, or to cap. DO NOT wear treated uniforms unless they are first thoroughly dried after treating. Apply permethrin outdoors or in well-ventilated areas only.

Blouse pants in boots and completely lace boots. Tuck undershirt in at waist. Wear sleeves down. Button blouse/shirt at the neck and wrist. Do not use aftershave lotion, cologne, or perfumed deodorants or soaps in the field; they attract arthropods. Wear headgear (cap, helmet, arthropod head net) when necessary to protect your head.



KEEP YOUR BODY AND UNIFORM CLEAN 
2-16

Bathe every day if possible, or at least once a week. Good personal hygiene practices reduce infestation of insects such as body lice and mites.

DunlapTattler.com public docs made public

FM 21-10/MCRP 4-11.1D



Wash your uniform frequently (a minimum of every 7 days) to remove arthropods and their eggs which may be attached to the uniform. If the situation permits, use the quartermaster laundry; otherwise, use a stream, lake, or washbasin. Air-dry uniforms, especially underwear and socks, if possible.

FOLLOW MEDICAL ADVICE   Take medications that help prevent diseases (such as anti-malaria pills) when directed by your commander. Use medications, such as cream/shampoo, when prescribed by medical personnel for treatment of lice, chiggers, poison ivy, and so forth.

PROTECT YOURSELF AT NIGHT    Ensure your bed net is in good repair. Use your bed net when sleeping. Tuck net under sleeping pad or sleeping bag so there are no openings.

Remove spiders from tents or buildings. Shake out and inspect clothing, shoes, and bedding before use. Eliminate collections of papers, unused boxes, scrap lumber, and metal. Thoroughly clean beneath and behind large items; spiders and scorpions may be resting in these areas.

DunlapTattler.com public docs made public

FM 21-10/MCRP 4-11.1D



Check field latrines before use; run a small stick under the rim of the latrine hole to dislodge any spiders or scorpions there. Spiders and scorpions may rest under toilet seat or inside latrine box. Wear gloves when handling paper, cloth, lumber, or other items that have been stored for long periods. Check around rocks and logs before resting against them. Use a long-handled tool or stick to turn over debris before removing it. Remove accumulations of boards, rocks, and other debris to eliminate the resting/ hiding areas of spiders and scorpions. Wear leather gloves to remove rocks, lumber, and such from the ground. NOTE In many locations worldwide, centipedes are more of a problem than scorpions, but the PMM are the same for both pests.

Avoid swimming in areas where snakes abound. Keep hands off rock ledges where snakes may be hiding or sunning. Look over the area before sitting down, especially if in deep grass or among rocks. If snakes are known to inhabit the area, sleep off the ground, if possible. If military situation permits, avoid walking about an area during the period from dusk to complete daylight, as many snakes are active during this period. Avoid camping near piles of brush, rocks, or other debris. Never step over large rocks or logs without first checking to see what is on the other side. Turn rocks and logs toward you when they have to be removed so you will be shielded should snakes be beneath them. Handle freshly killed snakes only with a long-handled tool or stick; snakes can inflict fatal bites by reflex action after their death.

DunlapTattler.com public docs made public

FM 21-10/MCRP 4-11.1D

NOTE If bitten, try to kill the snake and bring its head with you to the medical treatment facility. If you cannot bring the snakes head with you, get an accurate description of the snake to assist medical personnel in treating you. DO NOT panic! DOMESTIC AND WILD ANIMALS OR BIRDS    Do not handle or approach so-called pets. Exclude such animals from your work and living areas, unless cleared by veterinary personnel. Do not collect or support (feed or shelter) stray or domestic animals/birds in the unit area, unless cleared by veterinary personnel.

Section IV. POISONOUS PLANTS AND TOXIC FRUITS
OVERVIEW Many poisonous plants have thorns that can puncture the skin, introduce poison into the skin, or cause infection. (See FM 21-76.) Clothing can serve as a protective barrier for

the skin. Clothing can also be a source of exposure if it is not properly cleaned after contact with poisonous plants. Toxic fruits can also cause significant harm to service members, ranging from minor wounds to rapidly fatal poisoning. The threat is magnified for US military personnel who may be unfamiliar with native species and unaware of these poisonous plants and toxic fruits.     Avoid contact with poisonous plants by properly wearing the uniform. Avoid areas where poisonous plants grow. Only eat plants or parts of plants that have been approved. If you do not know, DO NOT eat it. DO NOT put grasses or woody twigs or stems in your mouth; they may be poisonous.

Section V. FOOD-/WATER-/WASTEBORNE DISEASE/ILLNESS
OVERVIEW Prior to deployment, the key to preventing illnesses and diseases from consumption of food and water is following the strict guidelines and procedures established by PVNTMED. During deployments, apply individual PMM. Infectious diarrhea results from contamination of water and food by bacteria, viruses, and parasites. Water- and foodborne

diarrheal diseases are of particular concern to the military because they can be spread to large numbers of service members simultaneously with disastrous consequences for combat readiness. Parasites (amoebas, Giardia, and tapeworms) consumed in water or undercooked food, especially meat and fish, can cause prolonged illness. Diarrhea, especially when vomiting or fever is present, can cause dehydration. WATER Fill your canteen with treated water at every chance. When treated water is not available, you must disinfect the water in your canteen using one of the following methods. Preferred methodiodine tablets:    Fill your canteen with the cleanest water available. Put two iodine tablets in the canteen of water. Double these amounts in the 2-quart canteen. Place cap on canteen. Shake canteen to dissolve tablets. Wait 5 minutes. Loosen the cap and tip the canteen over to allow leakage around the canteen threads. Tighten the cap and wait an additional 25 minutes before drinking.

Keep skin dry.   Use foot powder on your feet, especially if you have had fungal infections on your feet in the past. Use talcum powder in areas where wetness is a problem (such as between the thighs, and for females, under the breasts).

PREPARE FOR THE FIELD  All service members need to bring toilet articles such as soap, shampoo, washcloths, towels, toothbrush, dental floss and fluoride toothpaste, and talcum powder and foot powder, with them. Do not share these items to prevent the spreading of infections. Males need a razor and blades. Females need sanitary napkins or tampons. Remember, during a deployment, you may not be able to easily obtain these items if you run out; bring at least a 2-month supply.

Remember, consuming sugary food and drink requires more frequent cleaning of teeth and gums.

PREVENT GENITAL AND URINARY TRACT INFECTIONS For males:   Wash the head of your penis when washing your genitals. If uncircumcised, pull the foreskin back before washing. Protect yourself from sexually transmitted diseases (STD). Avoid sexual contact or use a condom; condoms reduce the chance of STD transmission.

FM 21-10/MCRP 4-11.1D

For females:      Wash your genital area daily. Do not use perfumed soaps or feminine deodorants in the field; they cause irritation and attract arthropods. Protect yourself from STD. Avoid sexual contact, or at least insist that your sex partner uses a condomcondoms help prevent STD transmission. DO NOT douche unless directed by medical personnel. DO NOT wear nylon or silk undergarments; cotton undergarments are more absorbent and allow the skin to dry. NOTE Some individuals do not drink enough fluids and tend to hold their urine due to a lack of privacy in the field. Urinary tract infections are one of the most frequent medical problems females face in the field. Drinking extra fluids and urinating more often will help prevent these infections.

SLEEP WHEN YOU CAN   Follow your leaders instructions and share tasks with buddies so everyone gets some time to sleep safely. Sleep whenever possible.


Take catnaps as the mission allows, but expect to need a few minutes to fully wake up. Sleep as much as you can before going on a mission that may prevent sleep. Learn and practice techniques to relax yourself quickly. NOTE Only sleep in safe and/or designated areas. Never sleep in parked vehicles while the motor is running.

 

MEASURES AGAINST THE EFFECTS OF SLEEP LOSS Protect against the temporary effects of sleep loss on alertness, mood, and task performance.  Take short stretch breaks or get light exercise in place.

FM 21-10/MCRP 4-11.1D



Do not trust your memory; write things down. Get into the habit of writing things down that you must remember (except crucial details that might compromise the mission if they were lost or captured). Double-check your communications and calculations. Watch out for your mind playing tricks (seeing things that are not there) when very tired; check strange observations before acting.



IMPROVE RESISTANCE TO STRESS  Fear and physical signs or symptoms of stress are normal reactions before and during combat or other dangerous/life-threatening situations. You should not let fear or stress keep you from doing your job. Talk about what is happening with your buddies, especially during after-action debriefings. Learn ways to relax quickly. Integrate new replacements into your group and get to know them quickly. If you must join a new group, be active in establishing friendships.

FM 21-10/MCRP 4-11.1D

  

M8 smoke is a very irritating gas. It can cause severe coughing, wheezing, and lung damage, if inhaled. Bore/gun gases cause the same effects as carbon monoxide and hydrogen chloride. Solvents, greases, and oils cause skin rashes, burns, drying, and infections. They cause damage to the liver, blood, and brain. Also, many are poisons that may cause cancer. Medical waste causes disease. Radioactive materials cause radiation illness.

 

PROTECT YOURSELF AND YOUR MISSION FROM TOXIC INDUSTRIAL CHEMICALS/ MATERIALS NOTE Service members should always be aware that material safety data sheets (MSDS) accompany stores of toxic chemicals when units are deployed, and they serve as an immediate reference in cases of exposure or injury. Once a unit is deployed and set up, these MSDS should be kept as part of the units SOP when handling the specified chemicals/materials.

     

The windchill index gives the equivalent temperature of the cooling power of wind on exposed flesh.


Any movement of air has the same effect as wind (running, riding in open vehicles, or helicopter downwash). Any dry clothing (mittens, scarves, masks) or material which reduces wind exposure will help protect the covered skin.





Trench foot injuries can occur at any point on the windchill chart and


Are much more likely to occur than frostbite at LITTLE DANGER windchill temperatures, especially on extended exercises/missions and/or in wet environments. Can lead to permanent disability, just like frostbite.



IDENTIFY SPECIAL CONSIDERATIONS  Conditions that place service members at high risk of cold injuries include

Ensure water trailers and tankers (400 gallon and above) are inspected by PVNTMED personnel semiannually. Inspect water containers before use. Check the residual chlorine of bulk water supplies (5-gallon cans, water pillows, water trailer) before drinking and at least daily thereafter. (See Tasks 7 and 8, Appendix A.)

Make sure foods, drinks, and ice purchased from civilian vendors are approved by the command medical authority. Supervise the use of the mess kit laundry/sanitation center. Ensure food service personnel and service members use handwashing devices. Ensure all food waste is transported to an approved disposal site, buried, or burned daily (at least 30 meters from food preparation area and water source).

PLAN FOR THE CONSTRUCTION AND MAINTENANCE OF FIELD SANITATION DEVICES  Determine type of field waste disposal devices required.


The primary type of human waste disposal devices in bivouac areas are the chemical toilets. Individual waste collection bags are the primary type used when on the march. The type of improvised waste disposal used will depend on the mission, length of stay in the area, terrain, and weather conditions. When chemical toilets are not available, the burn-out latrine is the preferred improvised waste disposal device.

PROMOTE COHESION WITHIN THE UNIT    Use equipment drills, physical fitness training, team sports, and field stress training to stimulate mutual reliance and closeness. Bring unit members together for meals, award ceremonies, and other special occasions. Integrate new members by assigning sponsors and ensuring rapid familiarization.

IMPART UNIT PRIDE   Educate service members in the history and tradition of the small unit, its parent units, and the branch of Service. Honor the historical examples of initiative, endurance, and resilience, of overcoming heavy odds, and of self-sacrifice.

Ensure that hearing conservation is part of the unit SOP. Ensure all service members are medically fitted for hearing protectors and are issued multiple sets. Ensure all service members have annual hearing test/screening. Control noise sources.
  

Isolate by distance; that is, keep troops away from noise, if possible. Isolate by barrier; for example, use sandbags. Use organic equipment controls; for example, keep mufflers and engine covers in good repair.

UNIT FIELD SANITATION TEAM
FIELD SANITATION TEAM CONCEPT  During World War II, it became apparent that more action was needed at the unit level to counter the medical threat. (Remember Togatabu Island and the jungles of Burma? [pages 1-2 and 1-3]) To answer this need, the FST concept was developed. Selected members from each company-sized unit were designated to receive special training in DNBI prevention so they could advise the commander in PMM for DNBIs. This training enabled the unit commander to provide arthropod control, individual and unit disinfection of water, and safe food supplies. This resulted in commanders being able to reduce DNBI losses.



SCOPE OF FIELD SANITATION TEAM OPERATIONS The FST  Conducts arthropod and rodent control operations in the field as directed by the commander. In garrison, the FST is in a training status. During mobilization, the FST performs its field sanitation duties.

 LICE:

DO NOT allow service members to keep pet animals.

STEP 1: Identify lice infestation:   Head licelook for lice and eggs attached to the hair, close to the scalp. Eggs are attached directly to the hairs. Crab liceusually associated with the pubic area (groin), but can be found attached to other body hairs. The eggs are attached directly to the hair. Body licegenerally found in the seams of infested persons clothing. The eggs are attached to the fibers of the garments. Body lice tend to move to the body of the host only during the actual feeding process.

Avoid walking through tick-infested areas. Cut down vegetation in and around camps. Enforce individual use of DOD insect repellent.

 

If necessary, have FST spray area with pesticide, using 1-gallon or 2-gallon sprayer to apply pesticide (see Task 2). Enforce a buddy system where troops perform checks not only on themselves but on their buddy as well. If ticks are found


Remove any attached ticks promptly and carefully without crushing, using gentle steady traction with forceps (tweezers) close to the skin to avoid leaving mouthparts in the skin; Protect hands with gloves, cloth or tissue when removing ticks from humans or animals; Ensure that the body of the tick is not separated from its head. NOTE





Lyme disease, Rocky Mountain spotted fever, ehrlichiosis, and encephalitis can be contracted through tick bites. Beware of ticks when passing through the thick vegetation they may cling to. When cleaning host animals for food, or when gathering natural materials to construct a shelter, you must be on the lookout for them. Buddy checks are important. If diagnosed early, the diseases mentioned above can be cured. If not, they can lead to death.

STEP 2: Control:    Remove, cover, or burn latrine waste. Keep food and waste covered. Use fly swatters for small to moderate numbers of filth flies. Only use the DOD-approved aerosol (Insecticide, d-Phenothrin, 2%, 12 ounce Aerosol, NSN 6840-01-412-4634) pesticide if large numbers of flies are in an enclosed area (do not use in food service operations). Ensure proper disposal of waste collection bags. Have FST use a 1-gallon or 2-gallon sprayer to spray pesticide on ground that is wet with kitchen waste, in field latrines, and on fly-resting sites (see Task 2). Use toxic fly baits.

STEP 2: Control:    Enforce good sanitation practices. Ensure proper collection and removal of food waste. Have FST use a 1-gallon or 2-gallon sprayer to spray pesticide as spot treatment in food service areas and as a residual spray to outside surfaces of buildings and trash collection points.

SPIDERS: STEP 1: Identify infestations of medically important spiders (black widow, tarantula, and brown recluse spider). NOTE Use caution when entering into and clearing out of old, infrequently used buildings.

DunlapTattler.com public docs made public

FM 21-10/MCRP 4-11.1D

 

The chlorine residual is below required level. A raw (untreated) or unapproved water supply must be used.

STEPS OF PERFORMANCE: STEP 1: Before adding chlorine, check the chlorine residual following the procedures in Task 7. STEP 2: If the chlorine residual is less than the desired level, add enough chlorine to raise the residual to the required level. Use Table A-1 to determine the amount to add to untreated water. If a 10 mg/L chlorine residual is required, double these amounts. To increase the residual in treated water, smaller quantities of chlorine will be needed. STEP 3: Wait 10 minutes, then check the chlorine residual. STEP 4: If the residual is less than 5 mg/L, repeat steps 2 and 3 using a smaller amount of chlorine. STEP 5: If the residual is at least 5 mg/L, wait an additional 20 minutes before drinking.
